Method for Generating Forward Error Correction Packet in Multimedia System and Method and Apparatus for Transmitting and Receiving Forward Error Correction Packet

1. A method for performing a forward error correction (FEC) encoding in a multimedia system, the method comprising: performing a first FEC encoding on each of source symbol blocks to generate each of FEC packet blocks and generate at least one first repair packet; and performing a second FEC encoding on the source symbol blocks to generate at least one second repair packet, wherein a repair packet of the at least one first repair packet includes information indicating a boundary of a FEC packet block corresponding to the repair packet.

2. The method of claim 1 , wherein the repair packet of the at least one first repair packet includes information identifying whether or not the repair packet of the at least one first repair packet is associated with a boundary of the FEC packet block.

3. An apparatus for performing a forward error correction (FEC) encoding in a multimedia system, the apparatus comprising: a first FEC encoder configured to perform a first FEC encoding on each of source symbol blocks to generate each of FEC packet blocks, and generate at least one first repair packet; and a second FEC encoder configured to perform a second FEC encoding on the source symbol blocks to generate at least one second repair packet, wherein a repair packet of the at least one first repair packet includes information indicating a boundary of a FEC packet block corresponding to the repair packet.

4. The apparatus of claim 3 , wherein the repair packet of the at least one first repair packet includes information identifying whether or not the repair packet of the at least one first repair packet is associated with a boundary of the FEC packet block.
